In 1988, 1,000 children became sick with polio every day. In 2002, the disease struck fewer than 2,000 people in the entire year.
The photographs of this work show some of the mass campaigns to immunize children against this disease in five countries at high risk of new outbreaks or where polio was stll endemic in 2001, the Democratic Republic of Congo, India, Pakistan, Somalia and Sudan. They also document the devastation caused by the disease.And they portray some of the millions who have contributed, in most cases as volunteers, by transporting the vaccine, immunizing children, and tracking new outbreaks.

A book, The End of Polio, was published in 2003, in five editions.
An exhibition of sixty images toured for several years.
